On the structure of brieskorn lattice
WebWe describe algorithmic methods for the Gauss–Manin connection of an isolated hypersurface singularity based on the microlocal structure of the Brieskorn lattice. They lead to algorithms for computing invariants like the monodromy, the spectrum, the spectral pairs, and M. Saito's matrices A 0 and A 1. These algorithms use a normal form … WebWe study the structure of the filtered Gauss-Manin system associated to a holomorphic function with an isolated singularity, and get a basis of the Brieskorn lattice Ω X, 0 n + 1 …
